Slow-Mode Magnetoacoustic Waves in Coronal Loops
Reale, Fabio; Srivastava, Abhishek K.; Ofman, Leon +3 more
Rapidly decaying long-period oscillations often occur in hot coronal loops of active regions associated with small (or micro-) flares. This kind of wave activity was first discovered with the SOHO/SUMER spectrometer from Doppler velocity measurements of hot emission lines, thus also often called "SUMER" oscillations. They were mainly interpreted a…
Linking the Sun to the Heliosphere Using Composition Data and Modelling
Del Zanna, Giulio; Wimmer-Schweingruber, Robert F.; Lynch, Benjamin J. +13 more
Our understanding of the formation and evolution of the corona and the heliosphere is linked to our capability of properly interpret the data from remote sensing and in-situ observations. In this respect, being able to correctly connect in-situ observations with their source regions on the Sun is the key for solving this problem. In this work we a…
